[Xenomai] Upgrading to Xenomai 2.6.1

[Doug Brunner <dbrunner@ebus.com>]

I've been having a very hard time with the upgrade from Xenomai 2.6.0 to 
2.6.1--hoping someone might have a suggestion for me. My thinking was 
that, to get the most possible bug fixes, I should also upgrade to the 
latest kernel for which there is a stable I-pipe patch, which appears to 
be 3.2.21 from examining the list of available patches distributed with 
Xenomai.

Unfortunately, 3.2.21 (even unmodified, using a vanilla Debian kernel 
config, set for 586 cpu type) will not boot on my target platform 
(Winsystems PPM-LX800-G, which has a Geode LX800 CPU). It immediately 
resets after "Loading initial ramdisk", without even any early printk 
output. I have no idea what could be causing that :(

I can't use CONFIG_MGEODE_LX because I get the following error building 
with the I-pipe patch:

arch/x86/lib/mmx_32.c: In function '_mmx_memcpy':
arch/x86/lib/mmx_32.c:33: error: 'ipipe_root_domain_p' undeclared (first 
use in this function)
arch/x86/lib/mmx_32.c:33: error: (Each undeclared identifier is reported 
only once
arch/x86/lib/mmx_32.c:33: error: for each function it appears in.)

and including <linux/ipipe.h> in mmx_32.c does not help.

I did see an email on the list suggesting that 3.4 is now supported, but 
if it is still in git and not released I'm guessing it hasn't undergone 
much testing yet. For a production environment, would I be better off 
just using 2.6.38.8?

I'd really like to get 2.6.1 running so I can see if it fixes the kernel 
oops I reported a few months ago.

Thanks,
